Readit NewsAnyway, locks and keys are inconveniences that keep people from casually abusing civil boundaries, is the point, and not all reasons for overcoming those are nefarious.
A covert camera placed near the keyhole is probably a better solution anyway, because most people don't flash their keys when just walking on the street (maybe when unlocking a car, but with keyless that's becoming rare).
Law enforcement can use pick guns, which will open a large majority of door locks, if they don't want to just use a battering ram for some reason.
There are a ton of legitimate reasons to use lock picks, though - being able to use a pair of paperclips, or office supplies, can get you into network cabinets in a pinch, or if you lock your keys in your house or car and have a pick kit in your wallet. If a friend has an emergency and they know you can do it, it can save locksmith fees. Kids can lose keys in astonishing ways.
And the hobby is fun - it's manual dexterity, skill, obscure technical knowledge, and you gain an appreciation for all the lockpicking content out there, and get to see the brazen plot devices when movies portray lockpicking in ridiculous ways. There are engineering attempts at creating unpickable locks with some awesome youtube videos, with engineering geeks creating elaborate locks and shipping them to the lockpickinglawyer or other content creators.
It's also important from an educational standpoint. Knowing how secure you are is important, because assumptions can lead to tragic results. If you have a glass door, it doesn't matter if you've got a million dollar unpickable lock. If you know how trivial it is to open most padlocks, and what form factors of locks are most susceptible, you can make better decisions about securing storage units, trailers, outdoor gates, bikes, and so forth.
A device like this is a novelty, not a serious security threat, and I'd argue the threshold for building it exceeds the threshold for which there are a thousand other trivially accessible ways of bypassing a given lock. There are tools similar to this device in spirit, in which you set pins for a key type manually with the key inserted, and with a little practice, will get you through a door in under a minute.

Rayleigh criterion: to resolve an angle of 4E-6 rad (key bitting step is 0.015inch =~0.4mm , two blocks is 2 * 200ft =~100m), you'd need a ~140mm aperture lens. Can you really buy one (with a camera no less) for $200?
See my other comment, pi5 2 GB is about ~10% more expensive then when 3 or 3b got released when factoring in inflation. ~60 EUR including 25% VAT.
With PSU it's 77 EUR including 25% VAT right now.
4 GB version + case + 64GB SD + PSU = 135 EUR, but I don't need that much ram, disk space or the case. When I put it into a 3d printer I also don't need the PSU.
Unless you want your printer to power up on demand, then you need a separate PSU and an SSR (and you still need a buck converter because printers don't supply 5V at required amperage).
I'm also currently building a small device with 5" touchscreen that can control a midi fx padle of mine. It's just so easy to find images, code and documentation on how to use the GPIO pins.
Might be niche, but that is just what the Pi excels at. It's a board for tinkers and it works.
This is here already. A long time ago, maybe even before covid, I asked a table of iPhone-owning friends who pays Apple a monthly sub for storage, and every hand went up.
I know you mention home computers, but most of my friends don't have one. Their iPhone is their computer.
You should look at a teardown of one of those sensors. It's a 1D lidar (if you can even call it that, until recently all of those were not ToF but more triangulation/reflection angle) being spun, no high res scans of anything can be achieved using that tech :)
(It’s important to distinguish it from the “buy drone-as-weapon at US retail, use drone inside US” threat model, but beyond telling them apart, I have no position prepared on the relevance of either model.)
pure idiocy.
You’d need a digital system with a gimbal, and the DJI O4 Pro alone will run you $200+. For dual lenses with different zoom levels and feed switching it’s getting pretty expensive very fast.
